temperature of yeast
My son has already turned in his idea to test how the temperature of yeast will affect bread. Initially he wanted 5 sep. temps for the yeast but thankfully his teacher got it down to 3 temps. Our plan is to have one package of yeast at room temperature, one in the freezer and one warmed in the oven. Any suggestions about procedures to ensure that our yeast is the correct temp. (how long should we freeze and warm the yeast? and does anyone have a simple recipe to use? Please help ASAP - our time line is lmited! Thanks ! lubencon

I'm not sure, but this is a suggestion
Um, when I did a experiment for yeast, I put it in the oven for about one hour. So, all of them should maybe be an hour.

i don't think you should put the yeast into the freezer, maybe the refrigerator and one more thing is that, if you are testing which yeast will make the best bread, then after the result, you have to explain why though, why the yeast at that temperature could make the best bread, if thats what you mean by hoe does yeast's temp,. affect bread :star:

good luck :star:

When you test something like this, don't go for the extreme temperatures where the conclusion is obvious. I agree that the oven should be substituted with the freezer. And the oven shouldn't be 200 degrees or higher. Because when the temperatures are so extreme, the yeast dies, and the dough ends up not rising at all.

When you're in doubt how long you have to wait, why don't you just try setting out the yeast and dough one time and see how long it takes to fully rise?
